Köttermann becomes an affiliate company of the Block group

With a solid economic position, Köttermann is directly owned by the BHM group a.s. to which the BLOCK Group also belongs.

At the end of June, the former parent company BLOCK Group a.s. sold its shares at the Köttermann company to the superordinate Czech BHM Group based in Prague.

Only four years after the insolvency, Köttermann and the Czech BLOCK Group are now equal in the portfolio of the parent company BHM group a.s. Tomas and Marek Krsek, who have been responsible for the successful corporate strategy since the takeover by the BLOCK Group, maintain their economic rights.

The growing economic importance of the Köttermann Group has made it possible to put Köttermann on equal footing with BLOCK Group a.s. The new organization is supporting the strategic management of Köttermann. The areas of sales, finance, insurance and risk management will be further strengthened and future growth will be favoured in the long term.

Köttermann GmbH has a technical managing director

Uetze, August 1st, 2019. Since August 2019 Köttermann GmbH has expanded its management by a technical managing director who, along with the Management Committee, has been working on the reorganization and group-wide pursuit of strategic goals.

Köttermann, as part of the BLOCK® Group, with 130 employees at the German headquarters in Uetze near Hanover, manufactures and distributes steel laboratory equipment “Made in Germany”. This includes fume cupboards, laboratory furniture, service supply systems and cabinets for hazardous substances. These products complement the portfolio of the BLOCK® Group, which includes clean rooms, isolators, process and healthcare technologies.

Freely adapted from Churchill’s quote “You do not solve any problems by putting them on ice”, we are happy that, with Jens Buchholz, a Swabian team player comes back to the Köttermann team. He had already worked in various functions and positions at Köttermann from 2005 to 2016 and distinguished himself over these years by strong implementation skills. In recent years, he has broadened his ample experience as Managing Director of Clestra Hausermann in Frankfurt.


“I am looking forward to this new task and the challenges associated with it. I am convinced that we will continue the success story of Köttermann after the years of reorganization”, says Jens Buchholz about his appointment.

“With Jens Buchholz, we have gained an experienced generalist for Köttermann, whose knowledge and experience we trust and will undoubtedly benefit from. I look forward to working with him and wish him every success in his new role”, said Jan Mynář, CEO of the BLOCK® Group.


Köttermann, part of the BLOCK® Group, since 2018, was founded in 1946 in Uetze (Germany) and is today an internationally recognized specialist for high-quality laboratory equipment made of steel. For more than 70 years, the company has been setting standards in terms of quality, safety, robustness and durability with its products “Made in Germany”. The company is represented at the headquarters in Germany by 130 employees. Worldwide there are partnerships in Central and South America, Asia, Africa and the Middle East.
